Hello! So the new faction related skins are a really great addition. However, it's annoying for people like myself who prefer using high-poly skin mods but unable to due faction restrictions to use specific skins. So, is there a way to mod the newly added skins? If so, how can we find their .txd and .dff in order to use our own models? Thank you!

Not sure exactly but I'm confident that you can use a TXD editor to recognize and find the right skin in the cache folder (mentioned above), once you find it, you may be able to mod it by using modloader, placing your modded FD skins in a new folder inside your install directory/modloader and renaming the txd/dff files accordingly with the names in the cache folder. If you replace the files directly in the cache folder they'll be re-downloaded when you log back in-game I'm sure.
